The radar

The Columbus AFB radar (KGWX), 96 km from the middle of the area, began a volume at 19:40 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Little Rock, AR (KBYH), launched 12:00Z, 7.6 hours before the alert went out and 154 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 19, 10:24 AM CDT, 4 hours 12 minutes earlier.

Area forecast discussion, Aug 19, 10:24 AM CDT, 4 hours 12 minutes before

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1024 AM CDT WED AUG 19 2015

.UPDATE...
THE WAVE OF TROPICAL MOISTURE IS CONTINUING TO SURGE NORTH-
NORTHEASTWARD INTO OUR CWA THIS MORNING. THIS WOULD BE THE SOURCE OF
ALL THE CLOUD COVER OVER THE AREA AND THE REASON WHY TEMPERATURES
ARE STAYING PRETTY STABLE IN THE LOW 80S AT THIS TIME. HIGH TEMPS
WERE CUT A FEW DEGREES TO KEEP HIGHS IN THE UPPER 80S TODAY. THE
POPS LOOK PRETTY GOOD...ALTHOUGH AFTER LOOKING AT RECENT MODEL RUNS
THE SEVERE CHANCES HAVE BEEN CUT BACK JUST A BIT. CONFIDENCE IN
SEVERE STORMS IS NOT AS GREAT. IN THE SW...THE BLOB OF RAINFALL WILL
KEEP THOSE AREAS PRETTY STABLE DESPITE A LITTLE BIT OF LIGHTNING
BEING ASSOCIATED WITH IT ALREADY. AS TO THE NW ALONG AND AHEAD OF
THE FRONT...THE MODELS ARE NOW HINTING THAT AFTER 00Z THE STORMS
WILL START TO DWINDLE SO THEREFORE HAVE REMOVED THE ELEVATED THREAT
AND STUCK WITH LIMITED. /10/

&&

.AVIATION...
THERE ARE A FEW PATCHES OF IFR CIGS THIS MORNING WITH
HIGHER CLOUD DECKS EXPANDING ACROSS THE AREA. SHOWER AND
THUNDERSTORM ACTIVITY IS EXPECTED THIS AFTERNOON AT THE TAF SITES
AND THE 18Z ISSUANCE WILL FOCUS ON TIMING AND ASSOCIATED
RESTRICTIONS ASSOCIATED WITH THIS ACTIVITY. /SW/

&&

.PREV DISCUSSION... /ISSUED 449 AM CDT WED AUG 19 2015/

SHORT TERM...THERE IS A CHANCE OF SEVERE STORMS FROM TWO SYSTEMS
TODAY AND TONIGHT. RIGHT NOW WINDS LOOK LIKE THE GREATEST RISK. AN
UPPER WAVE LOOKS TO MOVE OUT OF THE GULF THIS MORNING...BRINGING A
CHANCE OF STRONG TO SEVERE STORMS FOR THE ENTIRE AREA...BUT THE
SOUTHERN HALF OF THE CWA WILL BE MORE LIKELY TO BE IMPACTED.
CONVECTION WAS ALREADY BLOWING UP ALONG THE LOUISIANA COAST AND WAS
EXPECTED TO SPREAD NORTH AND WEST THROUGH THE MORNING. THE COLD FRONT
SHOULD MOVE INTO THE AREA TONIGHT. AHEAD OF THE BOUNDARY...MODELS
SUGGEST A LINE OF STORMS MAY DEVELOP AND MOVE INTO THE NORTHWESTERN
ZONES. THINKING THIS WILL BRING THE BETTER CHANCE OF SEVERE TO DELTA
IN THE 2Z TO 6Z TIME FRAME. WHILE WE ARE NOT IN THE MOST FAVORABLE
POSITION...BEING NEAR THE REAR EXIT REGION COULD ENHANCE STORM
DEVELOPMENT NORTHWEST OF THE CWA. MODELS SOUNDING SUGGEST THERE WILL
BE DECENT SURFACE BASED INSTABILITY...SO THERE SHOULD BE ENOUGH
ENERGY TO MAINTAIN STORMS. FOR THE HWO DEFINITELY GOING WITH LIMITED
ACROSS THE CWA FOR TODAY AND TONIGHT...WILL LOOK AT THE DELTA A
LITTLE CLOSER FOR TONIGHT. IT LOOKS LIKE THE BOUNDARY WILL HANG UP
AROUND HIGHWAY 82 AND LINGER THROUGH THURSDAY. FOR NOW IT LOOKS LIKE
GENERALLY THUNDERSTORMS DEVELOPING ON THURSDAY. MODEL PW VALUES
SUGGEST THERE COULD BE SOME HEAVY DOWNPOURS...WITH A BOUNDARY IN THE
AREA WILL NEED TO LOOK AT FLASH FLOODING POTENTIAL. FOR NOW WILL HOLD
ON ANY FLOODING IN THE HWO. HOWEVER...THINKING PONDING AND SOME
LOCALIZED FLOODING WILL BE POSSIBLE FOR THE NORTHERN ZONES. GUIDANCE
POPS AND TEMPS WERE GOOD.

LONG TERM......FRIDAY THROUGH TUESDAY...A QUASI STATIONARY FRONTAL
BOUNDARY WILL BE DRAPED OVER NORTHERN PORTIONS OF THE CWA AT THE
BEGINNING OF THE PERIOD...BUT IT WONT BE AROUND LONG AS UPPER SUPPORT
HAS PULLED AWAY AND UPPER RIDGE REESTABLISHES ITSELF OVER THE
NORTHERN GULF OF MEXICO. FOR FRIDAY ANYWAY...PROXIMITY OF SURFACE
BOUNDARY WILL PROMOTE ANOTHER CONVECTIVELY ACTIVE AFTERNOON OVER
CENTRAL AND SOUTHERN SECTIONS. MID 20S VERTICAL TOTALS AND LESSENING
WIND FIELDS SUGGESTS THAT THIS CONVECTION SHOULD REMAIN THE
DISORGANIZED PULSE VARIETY.

SURFACE BOUNDARY WILL MOVE NORTH OVERNIGHT FRIDAY LEAVING NO FOCUS
FOR CONVECTION SATURDAY. PWATS STILL RUNNING NEAR 2 INCHES SHOULD
SUPPORT A SCATTERING OF STORMS THOUGH. ONCE AGAIN...LIGHT FLOW
PATTERN AS UPPER RIDGE SHIFTS WEST TOWARD TEXAS SHOULD PROMOTE
ANOTHER DAY OF DISORGANIZED PULSE TYPE CONVECTION.

RIDGE CENTER WILL PULL FURTHER WEST INTO TEXAS OVERNIGHT SATURDAY
WITH INCREASED RIDGING OVER THE MID MS VALLEY. THIS WILL ALLOW A
KINK/SHORTWAVE TO FORM OVER THE LOWER MS VALLEY FOR SUNDAY FOLLOWED
IMMEDIATELY ON IT HEELS BY ANOTHER POTENT WAVE AND ITS TRAILING COLD
FRONT. THIS ACTIVE FLOW PATTERN WILL ALLOW DEEP LAYER SHEAR TO
INCREASE AS LAPSE RATES BECOME BETTER IN THE NW FLOW. AM STILL
CONCERNED ABOUT ROBUST CONVECTION SUNDAY AND MONDAY AS THESE
FEATURES INTERACT WITH THE AREA DURING MAX HEATING./26/
